Installation, Maintenance, Service & Part List Manual
• VGA cable: Carries video signals from the computer module to LCD controller board.
The LCD interface board gives the user the ability to modify the brightness,
color and position of the image.
• COM port cable Provides a serial communication link between the computer and the Overlay
Interface board.
•
overlay power
cable
Provides power to the LCD and Overlay Interface board. Also feeds back the
critical keys (GO, STOP, etc) to the computer module.
• EHW cable. Carriers the signals from the EHW to the computer module.
• Servo On Button Connects one channel of the servo on button to the computer module.
• USB cables (x2) Extend the two, USB ports on the computer module to the USB sockets on
the right side of the machine
A further 2 cables connect the servo on button and E-stop button to the E-stop safety relay in the electrical
cabinet.
2.3.2 Electrical Cabinet
The electrical cabinet is mounted to the rear of the machine. The electrical cabinet contains the main
control hardware for the machine. The main components are the computer module, AC spindle drive and
various fuses and relays. See drawing 27621-5 at the end of the manual.
2.3.3 Computer Module
The computer module is the heart of the machine. All of the inputs and outputs are fed through this
module. The computer module controls the programming panel assembly, AC spindle drive, servo drives,
motor signals and feedback and all the inputs and outputs. The computer module assembly comprises a
computer motherboard, applications board and power supply.
2.3.4 Servo Motors
The TRAK 2OP mill uses 3 servo motors with servo drives to run the X, Y and Z axes. The motors for the X
and Y axis produce 2.4Nm of continuous torque and 7.1Nm of peak torque. The Z axis motor produces
3.2Nm of continuous torque and 9.5 of peak torque. The servo motors run off of 220 volt, single phase
power.
2.3.5 Servo Drives
The TRAK 2OP mill uses 3 servo amps that are mounted in an enclosure that is mounted to the top of the
machine. The servo amps are the same for both the X and Y axis. The Z axis uses a larger servo amp to
drive the larger Z axis motor. A separate braking resistor is part of the Z axis servo amp circuit to dissipate
heat generated when the motor is decelerating. The resistor is mounted to the top of this enclosure.
2.4 Machine Major Sub-Assemblies
2.4.1 Spindle
The spindle is contained within a cartridge. The spindle bearings are permanently lubricated and require no
additional attention by the user. The spindle has an air purge system that is automatically activated during
the tool change sequence; it blows air down the spindle to prevent chips from being trapped between the
holder and spindle taper. The spindle cartridge design is also pressurized by air to prevent contaminants
from getting up inside the spindle. A spindle ring is also attached to the bottom of the spindle via the drive
dogs and prevents debris like coolant from getting up inside the spindle. BT30 tool holders must be used.
